Pictures of your mining rigs!

[pontiacg5]

So my power supplies are crap, should have known better...

I was looking into those power supplies, even went as far as pricing out all the molex connectors and pins I'd need. It is looking like a pretty attractive option considering what true 1300W power supplies cost. Is it easy as I imagine, just figuring out what is where and repining it?

Here's some mining results, after an hour or so. Fairly conservative settings, though the hashrate jumps around like crazy and some cards just seem much slower than others. I think I may still be dealing with power supply issues, or maybe driver issues? I'm not sure at this point 



Not very happy

I have a few more things left to try, but I went ahead and ordered some 7950's for this machine like I should have from the beginning.

can you give me a link of IBM BladeCenter on ebay, cant find it

http://www.ebay.com/itm/IBM-Bladecenter-13N0617-1800-Watt-PSU-/390320763039?pt=US_Server_Power_Supplies&hash=item5ae0ee309f

1800w but close.. "IBM bladecenter PSU"

Depends on your region. Their designed max load (in watts) varies with your countries line voltage and frequency. They are 2 KW where I live.

How did you convert their standard slot output to conventional molex connectors? Is there an adapter for that?

This is what I've been working on all weekend.

Winwoes is fighting like a beast, so I'm having to learn new things to get this going.

VVVVVVVVVVVVVVeeeeeerrrrrrrrryyyyyyyyyy nice!!!!

Congrats!

What hardware are you using? MB, GPus, etc.?

Like all things worth having, looks like this is one of those things you need to DIY. I've managed to find this...

That makes me think I should at least be able to get 12V from it. Finding the other terminals should be pretty easy once it's running.

This thread here is super handy, going to order all the pins and connectors from digikey
http://www.overclock.net/t/1136451/molex-atx-power-supply-connectors-and-part-numbers

Plan on just stealing 12V off the server power supply for the cards, then using a cheap 300W power supply to run the motherboard 

Does anyone know where I can find a PEG 8 pin connector? Molex doesn't seem to make them, though I have found the 6+2. No biggie, would just look "prettier" with the 8 pin.

[Trillium]

Yes it is definitely a DIY job. I am sorry if I mislead some others thinking you can just pick up a cable to convert it... you can't. There is lots of information and huge forum threads if you just google "hotswap psu pinout" and I can see you've already found some relevant threads.

The detailed way to do it is:

1. Make a strong double shot of espresso
2. Obtain multimeter, soldering iron
3. ....
4. Profit! Power!

I used the modular cables from a friends failed modular PSU to make the leads. It was a just a matter of desoldering the hotswap connector and soldering in the cables. I don't have that setup anymore but it was a IBM (Delta Electronics) PSU 2000 watt I'm pretty sure it was rated to put out over 120 amps 12v DC which should satisfy your needs. To power it on: find a ground pin (via traces) and then short it to all each of the smaller sense pins until it turned on. You could also look carefully at the traces as there are only a handful of them that lead to the 'smart' components of the circuit: most are current carrying for loads and connected to the high power electronic components.

Thank you for the lead Trillium, I'll post some results here in a few days once stuff starts showing up.

I just put in an order for $80 bucks worth of molex connectors and pins, and some good 18 gauge wire.

Now one last thing - finding a 220V cable to plug the supply in. Looks like the same connector as my 1500W EVGA supernova. Shouldn't be too hard 

[HellDiverUK]

That's a C19/C20 connection.  It's an easy-to-find cable, as most UPS over 2kVA use that connection.

[Trillium]

That socket is called a Type E  C19 16 amp IEC socket or also called "15 amp IEC" since they often come with 15/20 amp cable and 15 amp extra-large earth pin here in Australia.

Good electronics enthusiast & parts stores have them, or eBay, or any company specializing in cables. If your region has different sized or designed domestic mains outlets, you can sometimes find these high-amp cables in varieties that allow you to run them off 'normal' designed outlets (with the idea being the load is actually using fewer watts than expected and will NOT cause a fire to start somewhere or blow breakers).

[pontiacg5]

Thanks guys, I'll see if I can't find some of those at the hardware store here in town. Have a few days waiting for other parts to show up anyway.

The cable that came with the supernova is actually 110V, so the PSU is "rated" 1300W for losses on a 15A 110V US circuit. Supposed to do a full 1500W "overclock" at 220V though.

Wonder if the 1800watter would even turn over to ~1200W or so on 110v, sure would make it cost effective for the US guys that don't want to move the clothes dryer to mine

Hi there,

i got interested in Bitcoins and i ordered some USB Miners - i don't expect profit - i just do it for curiosity and hobby.

my Setup at the moment:

MSI u100 Netbook (Windows XP SP3) - admin via VNC
D-Link DUB-H7 - but will be replaced with 2x LogiLink UA0124 (after successful testing)
1 (perhaps 2) Arctic USB Breezers
I ordered 8 USB ASIC Miners for the first step

i suppose, that the first 5 USB Miners will arrive tomorrow - so i can start :-)
Already tried GPU Mining but with a geForce GTX660 it's a pain in the a**

perhaps i get a RaspberryPI for my birthday from my girlfriend *gg*

looks like your ready. Stick with the dlink hub but only put in 5 erupters into it. or look into the anker 9+1 hubs.

[ammi84]

my "8-stick-plan" is to use 2x LogiLink UA0124 (http://www.logilink.eu/showproduct/UA0124.htm?seticlanguage=en) with 2x4 USB Miners.
i will return the DLink Hub to Amazon

we will see if i buy more sticks in the future ... don't know
